Each time vintage and/or antique Tiffany solitaire lands on our laps, we are just beyond delighted! Rarer than rare, we love how these solitaires must have been kept in families for multiple generations, and are now ready to be your heirloom. The diamond is a beautiful old European cut that looks like a full carat in this setting. And the setting is the timeless 6-prong setting, with a platinum gallery and a yellow gold shank. In very good condition.

Size 7, and fully sizable.

Diamond measures 6.13 - 6.24 x 3.90 mm
